FileSystemWatcher Changed event is raised twice

Question

I have an application where I am looking for a text file and if there are any changes made to the file I am using the OnChanged eventhandler to handle the event

Answer 1

Try this, It's working fine

  private static readonly FileSystemWatcher Watcher = new FileSystemWatcher();
    static void Main(string[] args)
    {
        Console.WriteLine("Watching....");

        Watcher.Path = @"D:\Temp\Watcher";
        Watcher.Changed += OnChanged;
        Watcher.EnableRaisingEvents = true;
        Console.ReadKey();
    }

    static void OnChanged(object sender, FileSystemEventArgs e)
    {
        try
        {
            Watcher.Changed -= OnChanged;
            Watcher.EnableRaisingEvents = false;
            Console.WriteLine($"File Changed. Name: {e.Name}");
        }
        catch (Exception exception)
        {
            Console.WriteLine(exception);
        }
        finally
        {
            Watcher.Changed += OnChanged;
            Watcher.EnableRaisingEvents = true;
        }
    }
